Overview
The AD9283BRS-100 is an 8-bit monolithic sampling analog-to-digital converter (ADC) produced by Analog Devices Inc. This device is optimized for low cost, low power, small size, and ease of use. It operates at a conversion rate of up to 100 MSPS and features an on-chip track-and-hold circuit, making it suitable for a variety of high-speed applications. The ADC requires only a single 3.0 V power supply (operating range of 2.7 V to 3.6 V) and an encode clock for full performance, eliminating the need for external reference or driver components in many cases.
